Патогенез яичниковой беременности до настоящего времени не изучен. Существуют разные гипотезы механизма, препятствующего перемещению зиготы за пределы яичника: утолщение белочной оболочки гонады (воспалительного или иного генеза), патологическое ускорение развития и дифференцировки трофобласта, ввиду которого процесс имплантации начинается раньше времени, дисфункция фаллопиевых труб (нарушение перистальтики, захвата зиготы фимбриальными ворсинами, спазм).
Если яйцеклетка по каким-то причинам не вышла из разорвавшегося фолликула, сперматозоид может проникнуть в полость яичника, где произойдет оплодотворение, а затем прикрепление к фолликулярной стенке. Если выход яйцеклетки из граафова пузырька состоялся, но она почему-то не попала в воронку трубы, оплодотворение может произойти непосредственно в брюшной полости, после чего зигота внедряется в складки мезотелия на поверхности гонады.
Есть и другие версии прививки бластоцисты на поверхности яичника. Существует предположение, что большинство случаев поверхностной нидации является результатом полного трубного аборта живого эмбриона, а овариальная беременность – следствие его вторичной имплантации. Возможно, поверхностная имплантация обусловлена трансмиграцией оплодотворенной яйцеклетки – её переходом из контрлатерального органа через брюшную полость. Если к моменту достижения гонады бластоциста готова к нидаци, она может имплантироваться в яичник.
В норме эмбрион прикрепляется к слизистой оболочке матки, где обеспечены условия, как для его нормального развития, так и для защиты материнских тканей от деструктивного воздействия в процессе плацентогенеза. При эктопической беременности такие условия отсутствуют. Растущее яйцо растягивает и без того тонкие стенки плодовместилища, а инвазия трофобласта, сопровождающаяся выделением протеолитических ферментов, прорастанием ворсин, усугубляет деструкцию, приводящую к разрыву капсулы, внутрибрюшному кровотечению различной интенсивности.
